brcm47xx: sprom for nvram parsing

This adds support for parsing sprom form nvram for sprom version form 1 to 9.
It also adds sprom from nvram support for devices on the bcma bus.

+Subject: [PATCH 190/202] ssb: sprom fix some sizes / signedness
+
+Some parts of the sprom struct are bigger than needed.
+The leddc and maxpwr values are just 8 bit long and not 16.
+rxpo2g and rxpo5g are signed
+antenna_gain is unsigned
+
+I got these information for the open source part of the Braodcom SDK
+covering sprom version 1 to 9. rxpo2g contained a negative number on my
+bcm5354 based device, this cased an error and Broadcom SDK says this is
+signed.
+
+I was unable to find any reverences to antenna_gain.ghz5 in the
+Broadcom SDK.

+On SoCs the sprom is stored in the nvram in a special partition on the
+flash chip. The nvram contains the sprom for the main bus, but

+Subject: [PATCH 198/202] MIPS: BCM47XX: move and extend sprom parsing
+
+Move the sprom parsing from nvram into sprom.c. There are all values
+needed for sprom version 1 to 9 read from nvram and there are more
+sanity checks added. This is based on the sprom parsing in the open
+source part of the Broadcom SDK.

+Subject: [PATCH 199/202] MIPS: BCM47XX: provide sprom to bcma bus
+
+On SoCs the sprom is often stored in nvram in the flashchip. This patch
+registers a sprom fallback callback handler in bcma and provides the
+sprom needed for this device.
